Amelia Hiltshire's Links
Amelia is Isaac's only biological sister. She used to look up to him as a young child, but eventually grew to believe that he is a delinquent with no redeemable qualities. She disapproves of him the most out of their siblings. She has little to no faith in him and calls him “insufferable.”
Although she is a year younger than him and would prefer to not associate with him, she feels responsible for him and apologizes to everyone he comes in contact with. She also continues to remind him about work and what he needs to do, threatening to send letters home to their mother to report his bad behavior. Unlike Isaac, she doesn’t care about their biological father, choosing to dislike him instead for abandoning them.
Although Amelia may seem like a bully to her brother for no reason, she holds a grudge against him for abandoning his duties as a student. Amelia faced a lot of pressure from Alice because she did not want her to end up like Isaac. As a result, she was forced to miss much of her childhood to "clean up" what Isaac did, and become an academic champion. She tries to encourage Isaac to do better in his work and stop being a slacker to lessen the pressure on herself, but it comes out as condescending most if not all of the time.

Isaac attempted to reconcile with her and get her to at least tolerate him after being expelled from his school, claiming that he would never hate her, but to no avail. Now that he is more serious and self-assured at Hogwarts, he is not afraid to argue with her now. He is tired of her nagging and disapproval, and openly expresses his dislike for her, whether it be rolling his eyes when she talks or countering what she says.
Isaac misses his first year because Amelia was not present back then. He views her presence as a lingering, constant reminder that no matter what he does, someone would be watching him and making sure he didn’t screw up. Now that Amelia was in the the picture, he’d have to tiptoe around like old times. No more fun and messing around, or else she’d send a letter to their mother. He is not happy about having Amelia around.
However, when someone else tries to stand up for him or talks poorly about Amelia to him, he defends her, saying that "she's always like this, trying to look out for me. No big deal, it's okay."
